Exclude an object during serialization with XmlSerializer

I'm attempting to serialize an object but I would like to exclude one of the objects inside it. I've tried [NonSerialized] and it is still attempting to serialize it when I call XmlSerializer on a Cart object.

[Seriali开发者_如何学运维zable]
[XmlRoot("Cart")]
public class Cart : ICart
{
    // Public Properties
    [DefaultValue("")]
    public string ID { set; get; }

    [XmlIgnore()]
    [NonSerialized]
    public CartSerializer Serializer = new CartSerializer(this);
}

You may try to use XmlIgnore like this, it works!

    [XmlIgnore]  
    public string AnyProperty 
    {
        get;
        set;
    }
